OSError: Cannot load native module 'Crypto.Cipher._raw_ecb' on Apache mod_wsgi CentOS 8
I'm trying to run a django project on an apache server. The django server runs fine on its own but fails when running through mod_wsgi.

How to override Django get_search_results method in ModelAdmin, while keeping filters working as expected?
I have a Model admin where I override get_search_result this way def get_search_results(self, request, queryset, search_term): queryset, use_distinct = super(OccupancyAdmin, self).get_search_results( request, queryset, search_term ) search_words = search_term.split(",") if search_words: q_objects = [ Q(**{field + "__icontains": word}) for field in self.search_fields for word in search_words ] queryset |= self.model.objects.filter(reduce(or_, q_objects)) return queryset, use_distinct The suggestion comes from here: Is there a way to search for multiple terms in admin search? django The problem I am facing is the following: neither the DateTimeRangeFilter from rangefilter nor my custom SimpleListFilter work as expected anymore. The filters seem like being disabled. I looked at the SQL queries being performed and they seem alright. I am pretty sure I am messing up with the querysets somehow but don't know how to debug this. -
Django: Avoid duplicates image uploads from admin panel
I have a model with an ImageField, which allow an image upload from the panel admin of Django. I would like to check if the image already exists, before saving the model. If it's the case, I would like to display a popup (or a warning on the same page) with both images, to allow users to compare images, and allow saving if it's a false positive. For the image comparison, I'm going to use imagehash.average_hash() algorithm which gave me good results from my tests. So my questions are: How to get the file content (to compute the aHash), before the model save. How to display a popup or modify the modelAdmin page to allow the check of false positive. Any help is appreciated! -
How to count the value of dictionary using queryset in django
I used .value('post_id') in django to bring the following values. <QuerySet [{'post_id': 3}, {'post_id': 2}, {'post_id': 1}, {'post_id': 3}]> If you count the value of each dictionary, you will have one, one, and two, respectively. Which queryset should I look for, instead of counting it as a queryset without for loop ? -
Django - very slow annotation when annotation more than 1 field
I'm building a chat functionality for my django app. I made Message model, which looks like this: class Message(models.Model): sender = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, related_name='messages_sent', blank=True, null=True) receiver = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, related_name='messages_received', null=True) message = models.TextField(blank=True) created_at = models.DateTimeField(auto_now_add=True, db_index=True) Now I want to create a view with a list of users, ordered by the last message date with currently logged in user. def get_queryset(self): qs = UserModel.objects.all() user = self.request.user # exclude self qs = qs.exclude(pk=user.pk) qs = qs.annotate(last_sent_date=Max("messages_received__created_at", filter=Q(messages_received__sender=user))) qs = qs.annotate(last_received_date=Max("messages_sent__created_at", filter=Q(messages_sent__receiver=user))) qs = qs.annotate(last_message_date=Greatest('last_sent_date', 'last_received_date')) qs = qs.annotate(has_messages=Case( When(Q(last_received_date__isnull=False) | Q(last_sent_date__isnull=False), then=True), default=False, output_field=BooleanField() )) return qs.order_by(F('last_message_date').desc(nulls_last=True)) This was working very well, until I created many Message objects for 2 test users, each of them had 8k sent and 8k received messages (16k total). This slowed down the query significantly, and now it takes even 40-50 seconds (for small amounts it was below 500ms). After some investigation I discovered that the main problem is in those lines: qs = qs.annotate(last_sent_date=Max("messages_received__created_at", filter=Q(messages_received__sender=user))) qs = qs.annotate(last_received_date=Max("messages_sent__created_at", filter=Q(messages_sent__receiver=user))) Separately, they are very fast, but combined they are creating a very slow query. Is there some better way to annotate Max value from 2 fields or a way to annotate this … -

Django not accepting from that JavsScript has inserted a value into
I have a Django form uses FormBuilder.js. The intent is to use the JSON recieved from FormBuilder and have that JSON inserted into the JSON [Django] field using vanilla JavsScript (by directly setting it's .value). Django does not validate the form when using this method. However, if I hard type the JSON, or when the form fails and I return back to the page immediately, the form will validate. I have looked into the form itself on POST and the data is no different via any methods. Does anyone have a clue what's going on? -

In my Django-project how can I dynamically append a script which is located in the static folder to the head-section?
In my Django-project I would like to dynamically append a script-tag to the head-section. The script I want to append is located in static-folder. The problem is that I don't know how to reference the static-folder in javascript, or if that is even pssible. This is (a part of) my Javascript: jQuery( window ).on( "load", () => { const script = document.createElement("script"); script.src = "{% static 'js/myScript.js' %}"; document.head.appendChild(script); }); myScript.js could look like this: console.log("This is myScript") Of course this does not work. In the console I get: GET http://127.0.0.1:8000/%7B%%20static%20'js/myScript.js'%20%%7D net::ERR_ABORTED 404 (Not Found). Is there a way to reference the static-folder inside a javascript? -
